PED-SIG
•Mobile Accessible
Pedestrian Signal System
•Problem
Addressed:
–Many legacy pedestrian
signals at traffic signals are not accessible to pedestrians with visual
impairments, auditory systems have drawbacks
•Description
–Mobile devices carried
by visually impaired pedestrians receive SPaT data broadcast in signalized
intersections
–Orients intersection and
crosswalk geometry, as well as intersection status
–Mobile devices also
broadcast messages to make enabled vehicles aware that a pedestrian is present
in the case of blocked line-of-sight
